Abstract
Integrated regulators are used for power management in modern portable devices. There are many primary regulators and post regulators which converts high dc voltages, but they are unable to work on low voltage with low quiescent current. A low-voltage low-dropout regulator with current splitting technique is proposed which converts a low-voltage of 1V to an output of 0.6 V with 90 nm CMOS technology. A power noise cancellation mechanism is formed at rail-to-rail output stage of error amplifier (EA) which minimizes the size of power MOS transistor. A transient accelerator (TA) is formed to reuse the part of EA which achieves high current efficiency.
